Figures on neuropsychiatric rejections, hospital admissions and separations from the army are given with the warning that administrative factors must be taken into account before conclusions as to their significance can be drawn. Some thirty-seven percent of all rejectees and forty-one percent of all medical discharges were made on the basis of neuropsychiatric diagnoses, while an additional one hundred and thirty-seven thousand men were discharged because of mental deficiency and psychopathic personality. The daily average official incapacitation of army personnel for neuropsychiatric disorders was six tenths percent of the total forces. This data does not include outpatient cases.
